Technical Overview

KerfScript is a programming language built for digital manufacturing and laser cutting. It enables engineers and designers to write parametric 2D designs featuring cut, score, and engrave layers, automatic kerf compensation, joinery, and sheet layout. Users can export their designs directly to standard SVG or DXF formats for production in fabrication shops.
